Appneation inea August 12,1922. serial No. 581,426.

To all whom it may concer/n.'

' Be it known that I, STANLEY D. HUM- Pmuns, a citizen ofthe United States, residingl at city of Flint, inthe county of Genesee and State of yMichigam have invented certain new and useful Improvements in Machines-for Making Asphalt Pavements and the like, of which the following is a specification.

This invention relates to machines for making asphalt pavements and the like and has for its object to provide a machine of such class, in a manner as willbe hereinafter set forth, first, with means for spreading the `material, forming the pavement body, to overcome the y employment of shovels and to dispense with the walking on and tramping down of the surface by thelaborer's vwhen using shovels for spreading the material; with means to thoroughly comb or rake` the material after being spread, and, with means for leveling or grading tothe degree desired.

Further objects' of the invention are to provide a machine `for the'purpose set forth whichis comparativelysimple Vin its construction and arrangement, portable, strong, durable, efficient in its use and comparatively'inexpensive to set up and o-perate.

With they foregoing and othery objects in view, the invention consists of a novel con'- `struction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but itis to be understood that changes, variations and modifications can be resorted to, which fall within the scope of the claims hereunto appended. n

` Figure 20, isa side elevation ofFigure 19. Figure `21 is a detail of the operative drive connection for the forward spiral.

The machine isyportable and is adapted to travel on the curbing of a road surface.

The machine includes a body portion rec- A, tangular in contour, formed from suitable beams connected together in anyV suitable manner, and havinlthe front thereof provided with inwar y` extending axles 2,

carrying flanged wheels 3, adapted to travel on the curbing of the pavements or road bed. The rear of the body 4lcarries a pair of inwardlyy extending axles 4, each'provided with a flangedy wheel 5y and a gear wheel 6 the latter has meshing therewith a gear 7 carried by an axle 8, 'supported from the body 1. Meshing with the gear 7 is ya gear 9, carried b the axle 10 mounted at the rear of the bo y 1.

At the rear of the body 1 a pair of shafts 11 are supported therein, and each of said shafts 11 on its outer end is provided/with -a pinion 12 which meshes with and drives the gear 10, whereby through a medium of the gears 6 and 7, the rear wheels 5 are operated so that the machine will be driven adapted to mesh with a bevel pinion 16, on

a countershaft 17, operated from a drive shaft 18, the latter is driven from a prime mover, (not shown). The other shaft 11 has its inner "end Vprovided with a bevel gear 19, which meshes with bevel pinion, carried by a transmission shaft 22, operated from a. pinion 23, carried by the countershaft 17, and which meshes with and drives a gear. 24, on the inner end of the transn mission shaft 22. Countershaft 17 and transmission shaft 22 are supported by the bracket 25 mounted on the platform 13. A clutching mechanism 26, operated by a lever 27, is employed for connecting the countershaft 17 and the drive shaft 18.

The body 1 is supported over the road bed lorpavement by the lianged wheels 3 and 5 which travel on the curbing of: the

. pavement and at the front of the body 1 a spreader 28 is secured, which 1s V-shape in contour and is employed for spreading the material to form the .road bed or surface prior to the action of the rakes and templets.. vThe spreader 28 is secured to the body l, by forwardly proj ectingvbrace members 29. The machine is driven forward to cause the action of the spreader 28 on the y material to spread the latter.

The machine embodiesl a series of vwhat may be termed vforward rakes, which are adapted to comb out and make flaky the materialfrom which the road bed is made, preparatory to the action of they templets.

n The forward rakes are set up whereby they will be actuated in opposite directions relative to each other, and in a direction transverse with respect to the pavement or road bed. Two sets of forward rakes are employedand eachforward rake of each set consists of a transversely extending carrier `30, provided with a series of tines 31.

Each set of forward rakes has associated therewith 'a' pair of coupling bars 32, 33, and a pair of couplingbars 34, 35. The bars 32 and 33 associate and are secured to alternate carriers 30.0f the forward rakes and the bars y34, 35 associate and are connected to the other carriers 30 ofthe forward rakes. Secured to the body 1 are slotted guide plates 36 into which extendv and travel rollers 37 carried by the ends of the outer bars 33`and 35. Secured tothe body 1 are slotted guide plates 38 into which extend and operate rollers 39 carriedby the ends of the bar 32. Projecting upwardly of the bar 32 is a lug 40 toy which is pivotally connected a link 41, which isattached to an eccentric 42 on the shaft 43. Projecting upwardly from the ybar 34 is a lug 44 to which is pivotally connected Aa link 45 which is attached to an eccentric 46 carried by the shaft 43.k kAn eccentric 42 is employed for use in connection with each bar 32 and an .eccentric 46 is employed for use in connection with each bar-34. When the eccentrics are operated owing to the manner in which the carriers of the rake are connected therewith, alternate rakes of'each set move in opposite directions, but the rakes of each set travel transversely of theroad bed or the pavement and impart a thorough raking action to the material.

The shaft 43 is driven from the shaft 22 and to provide for this operation, the forward end of the shaft 22 is connected with a shaft 43 'by a chain drive 47.

Each set `of forward rakes are vertically adjusted and vfor thisf purpose vertically movable hangers 48 are provided and which are vertically adjustable, by the screw49 engaging with the hangers .48, and which are provided with bevel pinions 51 carried on the ends of the shaft 52, the latter is supported by the bracket 53. One of the screws 49, is extended as at 54 and provided with a handle 55 whereby the screw can be rotated, causinga like operation to the other screw 49 as is obvious whereby the hangers 48 will be adjusted carrying the set of rakes therewith. Y

At the rear of the forward rakes, what is templets are arranged inV a set preferably a three in number but thev number can beincre'ased or diminished if desired, as illustrated three forward templets are employed, as indicated at 56, 57 and 58. The templets 56, 57 and 58 are arranged whereby the forward tem let is shorter than the intermediate temp et 57, the latter is shorter than the rear templet `58. They templets 56, 57 and 58 are secured by angle arms 59 to a pair of pivoted supporting arms 60. The arms 60 are pivoted as at 61 to a bracket 62 secured to the body 1, each arm 60 carries an adjusting screw 63 for regulating the position of the templets 56, 57 and 58 with respect to the surfaceor road bed. The

screws 63 associate with a anged portion V64, of the body 1, which acts as a stop and su port for the screw 63.

ounted on the body 1 is a pair of brackets 65 which support a rock shaft 66, the latter has each end provided lwith a groove collar 67 carrying a chain 68, which is attached to an arm v60. Fixed to the shaft 66 is a lever arm 69 which is used to each rear set .consists ofy a carrier 71 :pro-

vided with a series of tines 72. Each set of rear rakes does not move laterally or transversely but is adjustable vertically, and

ated on by the templets.

these rear rakes only operate as machine travels forwardly and rearwardly. Each set of rear rakesfhas its'inner'ends provided with a pair of hangers 73, eachof the hangers are engaged by `an adjusting screw 74, provided with a bevel `pinion k75, which meshes with a bevel gear 76 on the end of the shaft 77, one of the screws 74 is extended as at 78, and provided with a hand 'wheel 79, thereby to enable the operation of screw 74 causing the'operation of the other screw 74 and the adjusting lof the setfof rakes. The outer end of each set of rear rakes has a coupling member 80, which is mounted in the body `1 and provides means whereby the outer end of the set can pivot when the inner end is adjusted. The'inner end of'eachset of rear rakesvis connected together by a coupling bar 81, but this bar 81 isnot seated in the'body 1.

The body portion 1, rearwardly'` of the rear rakes has f arranged therein the rear templets which are indicated at 82, 83 and 84, these latter are connected by' angle arms 85 to a platev 86 which is carried by an arm 87 pivoted as at 88 to the body 1. Two arms 87 are employed. At the rear of the body 1 afshaft 89 is arranged and which is supported by the brackets 90. Each end of the shaft 89 carries a grooved collar 91 to which is attached chain 92,

the latter 'being attached to the templets' 82, 83 and 84. A lever 93 is employed for rocking the shaft 89 so as to elevate or lower templets when desired.

The rakes as well as the templets conform in contour to the surface of the road bed and the rakes or templets, owing to the manner in which they are set up, can be adjusted relative to the road bed. y

In Figure 15, the 4construction of each templet is illustrated as formed from a singie piece of material having the lower portion curved to conform to the surface of thev road bed, but it is obvious that instead of constructing the templet from a Single piece of material it can be made from a series of tines, as illustrated at 94, Figure 14.

As the'machine advances toward the pile of material, the material is spread vby the spreader and following this spreadin operation it is subjected to the forwar rakes which are so set up that the rakes with parallel groups of tines are moved simultaneously in opposite directions. After the raking operation, the surface or material is oper- Following this the rear rakes operate upon the material or surface when the machine is moved rearwardly or forwardly and after which the rear templets are thrown into operation.

In Figures 19 and 2G, the machine is shown as provided forwardly of the raking elements. with material feeding or distributing elements in the form of spiral rollers.

The lineal contour of such elements maybe either straight or concave lto give the approximate crown ofy the road. The spiral rollers are so formed that they feed or distribute the material from the center out towards either side. The rollersV may ybe stzionary as shown, or adjustable vertica In Figures 19 and 20, the forward part of the machine framev is indicated at 95 and the spiral rollers at 96, 97.l i

The roller 96 is of a lengthsubstantially to extend from near one side to the other side of the machine frame and is provided at eachend with a spindle 98, only one shown, and which are journaled inthe sides of the .machine frame. The roller 96, intermediate its ends is operatively connected, as at 99 to a drive shaft 100 therefor.

,A pair of rollers 97, are employed, only one of which is shown, and veach of the rollers 97 extend rearwardly at an inclination. The roller 97, is supported at its outery end in a pivotal bearing 101. The bearing 101 is secured to the inner face of the side. of the machine frame. The inner end of the roller 97 is supported, as at 102, from a frame bar103, and is connected by a universal joint 103, to a driving' element 104, therefor. element 104, are actuated from any operating means 105, which is operatively connected as at 106,with the driving means for the other elements ofthe'machine.
